I do not hide that for me this is a step forward in my career in every way. It is a reward for my work, my effort, and it is a unique opportunity that any player would like to take. I came to Valencia five seasons ago and this transfer would be benefit all parties involved. During my time here I have always tried to do my best but it's time I moved forward and ended a cycle which I will always carry in my heart. I will be eternally grateful no matter what.

But still the clubs would not budge on their respective positions, until Valencia announced that they were dragging Mathieu halfway around the world to play.

Barcelona, obviously concerned about the effect the World Cup has had on their players, have picked pre-season games based in Europe only.

They would also want Mathieu to have as much time as possible adjusting to his new life in Barcelona, and the way you have to play while with the Blaugrana.

Being a central defender at Barcelona is considerably different than at most other teams.

You need to be high up the pitch and always concentrating so you don't get caught out on the break.

Valencia knew all this so they were in a commanding position during the transfer negotiations.

Barcelona's hand was also forced by other defenders slipping out of their reach.

The likes of David Luiz and Marquinhos were long-term targets, but the former moved to PSG and the latter would have cost too much money.

There were few other options, with Jurgen Klopp ruling out the idea of Mats Hummels moving away.

In the end, Barcelona were left with one choice. And so Valencia made them pay the full price.

Mathieu's move is now the most expensive transfer of a defender aged 30 or over.
